Title: Production of optical film and apparatus for production therefor
Inventor: MIYAZAKI MASAAKI
IPC: G02B5/126
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To obtain a high-quality optical film with a simple treatment by swelling the surface of a base by using a solvent to make the surface tacky adhesive, adhering beads to the surface and removing the beads not adhered thereto. SOLUTION: The base 21 is immersed into the solvent 24 housed in a vessel 23 by a roller 22. The base 21 of which the surface is thereby swollen and made tacky adhesive is further brought into contact with the beads 25 settled on the bottom of the solvent 24 by the roller 22. The base 21 adhered with the beads 25 in such a manner is passed through the solvent 24 again by the roller 22, by which the excessively adhered beads 25 are removed. In such a case, the beads 25 are composed of microparticles of a transparent base stock. Glass or plastic is used as the transparent base stock. Generally, the glass is more preferable than the plastic. The shape of the particles is preferably nearly spherical. While the particle size of the beads 25 is determined according to the application of the optical film, the beads are required to be the smallest possible particles.

Title: Electromotive force displaying apparatus for battery
Inventor: KIMURA SHIGENORI
IPC: G01R31/36
Filed: 1992-06-04
Abstract: PURPOSE:To display remaining capacity of electromotive force of a battery so that it can be correctly recognized by providing a displaying and correcting means for correcting a voltage value between terminals according to magnitude of a load current value and displaying the corrected value. CONSTITUTION:A controller 8 is equipped with a voltage detecting means 14 for detecting a voltage value between both terminals of a battery 7 while a load current value of an electric motor 3 detected by a load detecting resistor 15 is input to it via an amplifier 16. The load current value is compared with a reference value set by a reference signal generating means 18, wherein a correction signal is output from a corrected signal generating means 20 before the voltage value between terminals is input to a driving signal generating means 21 so that the larger the difference signal the larger an actually measured voltage value. Thus even if load to a motor 3 is excessive and the voltage between the terminals of the battery 7 drops due to an effect of an increase in motor 3 current, the drop is corrected by a display correcting means 22 for making display 3, so that remaining capacity of electromotive force of the battery 7 may not be erroneously recognized.

Title: Automatic steering device for car
Inventor: ONO MAKOTO
IPC: B62D6/00
Filed: 1983-08-05
Abstract: PURPOSE:To drive a car on a driving lane with no handle operation by keeping the distance detected by a distance detecting means at a prescribed value with the function of a steering angle driving means using a steering angle control signal. CONSTITUTION:While a car is running on a highway, the image pickup signal of a right camera 3 is supplied via an A/D converter 7 to recognize a center line. Then a side line is recognized in the same way by the image pickup signal of a left camera 4. Then the distances D2 and D1 between the center position of the center line and each inside end of both right and left areas. Thus the distance deviation DELTAD=(D2-D1)/2 is obtained. Therefore, it is possible to drive a car at the center position between both lines by changing the driving direction by deviation DELTAD. Then an angle deviation DELTAtheta is obtained from DELTADXalpha (constant) and is added with the steering angle data A obtained from an angle sensor 6. Thus a target angle theta is obtained. Then a drive control command is given to a steering angle driving actuator 1 so as to obtain coincidence between th data A and the angle theta. Thus it is possible to drive a car as desired.

Title: Radiation thermometer
Inventor: TAMAGAWA YUKIHISA
IPC: G01J5/00
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To suppress errors in approximation generated by a change in wavelength characteristics in company with a change in temperature of an object to be measured by calculating temperature of the object to be measured with use of a specified equa tion from a detection signal corresponding to a radiation quantity of light. SOLUTION: An optical detecting means 1 detects a radiation quantity of light from the object to be measured and outputs a detection signal V. A calculating means 2 calculates temperature T of the object to be measured from the detection signal V supplied by the optical detecting means 1 based on an approximate equation in which the detection signal V is shown as a function of T to the ath power (0<a<1), wherein the function has temperature of the object to be measured as a base. In an equation [1] of Planck's law of thermal radiation, Wλ =C1 ÷λ<5> exp(C2 /λT)-1 (wherein W is a spectral emmisivity, λ is a wavelength, T is temperature, and C1 and C2 are constants) errors are suppressed in such a manner that an influence of a change in λby temperature is absorbed by temperature as a variable, corresponding to fixing of λ.  A relation between V and T is set by making a part λT of the equation [1] corresponding to a term which expresses a function which has an upward concavity, that is, an exponential term having temperature T as a base (an exponent a3 is 0<a3 <1).

Abstract: PURPOSE:To eliminate limitation on an operation for training by suppressing the movement of information when a training mode is designated by moving a hard total (HT) working area to an HT storage area when no training mode is designated, and returning it to its original position after a transaction is completed. CONSTITUTION:A training mode flag is set at a RAM 7 when a training mode switch on a panel 14 is activated. Meanwhile, when no operation of the training mode switch is performed, the training mode flag is reset. Next, an establishment processing is executed, and when it is completed, POS terminal equipment 1 can perform the transaction. When no training mode is set at the RAM 7, the HT in the HT storage area is transferred to the HT working area. Meanwhile, when the training mode is set, a processing is migrated to the next processing by omitting a moving processing. At this step, the kind of sale, the inspection, and the account of goods, etc., can be decided, and the operation of the transaction, etc., can be performed without setting limitation similarly as an ordinary mode(sales mode).

IPC: B29D30/04
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tyre which can restrain the generation of an eccentric wear and show a sufficient on-ice performance after a middle stage of wear. SOLUTION: A cap part 12A is formed by a foaming rubber with a spherical independent foam and a base part 12B has the spherical independent foam and long independent foam 24 covered by the protection layer 26 of resin and is madely a foaming rubber exposed after a wear middle stage. As the long independent foam 24 covered by the protection layer 6 is hardly crushed, the rubber of the base part 12B is hardly deformed. The block 18 after the wear middle stage is nearly the rubber of the base part 12B and is hardly shearing- deformed and the eccentric wear is restrained. The long independent foam 24 exposed on a tread surface removes the water in a contact ground surface efficiently by performing the duty of a drain.  As the eccentric wear is restrained after the wear middle stage and also the draining operation by the long independent foam 24 is obtained, the sufficient on ice performance after the wear middle stage can be shown.
